W.|NDOW-SASH FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 519,607, dated May 8, 1894.

Application filed October 26, 1893. Serial No. 489,205. (No model.)

Be it known that I, RICHARD KIRSOH, of Bay Ridge, in the 'county'ofKings and State of New York, have invented a new and ImprovedWindow-Sash Fastener, of which the iollowing is a full, clear, and exactdescripion.

My invention relates to a window sash fastener, and it has for'itsobject to provide a fastener adapted for use in connection with pivotedwindow sashes, primarily those sashes which are pivoted at their centersat top and bottom.

Another object of the invention is to pro vlde a fastener of the abovetype, which will be exceedingly simple, durable and economic, and whichwill be capable of expeditious and convenient manipulation and capableof attachment to any window of the center pivot type, without detractingfrom the appearance of the window. I

Theinventionconsistsin the novel constructron and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar figures and letters of reference indicatecorresponding'parts in all the views.

Figure 1 is a front elevation of a window having the improvementapplied. Fig. 2 is a vertical section taken through a portion of.

the window frame, showing a portion of the sash in side elevation, andlikewise the attachment, the section being taken on the line 2-2 ofFig. 1. Fig. 3 is a horizontal section taken through the window frame,practically on the line 3-3 of Fig. 1, and illustrating the attachmentin plan view. Fig. 4 is a vertical section through a portion of thewindow sash and a portion of the attachment, the section being taken onthe line 4-4 of Fig. 3. Fig. 5 is a sectional view through a connectingblock adapted to unite members of each other; and Fig. 6 is a frontelevation of the lower portion of the attachment, illustrating themanipulating or looking lever in a position to effect free movement ofthe window sash.

The invention consists primarily of a looking lever A, an operatinglever B, and aconnecting rod 0, establishing communication between thetwo levers. The above named parts are adapted to be located upon thewindow sash D, and to operate in conjunction with a rack E, to beattached to the window frame E. The locking lever is located upon thetop rail of the sash,.and extends across the upper portion of one of theside rails, and upon that side rail the connecting rod 0 and theoperating lever B, are to be located.

' The locking lever A, is passed loosely through a block 10, the blockbeing apertured to receive the lever; and the lever is held fixedly inthe block 10 after it has been adjusted, through the medium of asetscrew 11, passed through the block to an engagement with the lever,as shown in Fig. 4. The block 10, is adapted as a pivot for the locklever, and to that end the block is provided with a shank 12, and thesaid shank is held to turn loosely on or is pivoted'in any approvedmanner in a plate 13, the plate being adapted for attachment, throughthe medium of screws or equivalent fastening devices, to the windowsash. The lock lever is likewise provided with a guide 14, which guideis of a bracket-like character, being open at the bottom, and the saidguide bracket is secured to the window sash, and the lever has verticalmovement in the bottom opening in the said guide.

At or near the inner end of the lock lever, a locking pin 15, islocated, the said locking pin being made in two diameters, whereby ashoulder 16, is formed near its upper end; and the locking pin isfurther provided with an enlarged base 17, and the base is provided 7with an opening through which the lever is passed. The base isadjustable upon the lever, and may be held stationary at any point uponthe lever through the medium of an adjusting screw 18. The upper orreduced end of the locking pin' is adapted to enter-any one of a seriesof apertures 19, produced in the rack E. The rack is horizontallylocated near the upper central pivot of the window sash, being securedto the window frame; and the rack is preferably of a quadrant form, andone memher is located sufficiently close to the upper pivot of thewindow sash to allow said window sash, when opened or carried at rightangles to the window frame to engagewith a flange 20, projected downwardfrom the said inner member, which flange will serve as a stop andprevent the window from passing over a center line when opened.

The outer end of the locking lever A, is reduced in diameter, as shownat 21 in Fig. 3; and the said reduced portion 21, is preferably circularin cross section, while the remaining portion of the lever is more orless rectangular in cross section. The outer extremity of the lock leveris threaded to receive a nut 22, and the circular or cylindrical end ofthe lever is made to pass loosely through an opening 23 made in ablock24, which opening is flaring at both of its endsin order that whenthe block is moved in a vertical direction the lever A, which stands atan angle to the block, may be moved at its inner end upward or downward,as shown in positive and in dotted lines in Fig. 1, thereby carrying thelocking pin 15 either to an engagement with the rack or out ofengagement therewith.

It will be observed that the locking lever A, is capable of a lateraladjustment both in its pivot block and in the end block 24, which may betermed a connecting block, since the said block is attached to theconnecting rod 0. And it is likewise evident that the looking pin hasindependent adjustment upon the lock lever, so that the pin and thelever may be adjusted to suit any emergency or any condition under whichthey may be used.

The connecting rod 0, is held to slide in one or more guides 25, securedupon avertical rail of the window sash, and the lower portion of the rodhas guided movement in a plate 26, the lower extremity of the rod beingpreferably provided with a head 27, adjustably located thereon. Theoperating lever B, is pi voted in the plate 26; and the said operatinglever is an elbow, an angle or a crank lever, one of its members, itspivot member, being much shorter than its.outer or handle memher; andthe lever at the junction of its two members, is bifurcated to permitthe passage of the connecting rod, and the head of the connecting rod isconnected with the operating lever at the junction of its two members,through the medium of links 28. The operating lever is so placed in theplate that when the handle member of the lever is carried to ahorizontal position, as shown in Figs. 1, 2 and 3, the handle section ofthe lever will have such bearing upon the head of the connecting rod asto carry the said rod downward,locking it in its downward position,which movement also causes the outer end of thelocking lever to be drawndownward, and the locking pin carried by the lever to be forced upwardin the aperture'in the rack. The locking lever will then be in ahorizontal position at right angles to the connecting rod, and thewindow will be looked in an open, a partially open, or 1n a closedposition as may be desired.

When the handle end of the operating lever is carried up to the verticalposition shown in dotted lines in Fig. 2 and in positive lines in Fig.6, the connecting rod is carried upward, and the inner end of thelocking lever is carried downward, thereby removing the locking pin fromengagement with the rack E, and permitting the window to be swung uponits pivot.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a window sash fastener, the combination, with awindow frame, a window sash pivoted in the said frame, and a racklocated upon the frame adjacent to the pivot of the window sash, of alock lever located upon the sash, the said lever being adjustableuponnts fulcrum, an adjustable locking pin carried by the lock lever andadapted for engagement with the rack, an operating lever also adaptedfor location upon the sash, said locking lever being of angularconstruction, a connecting rod projected from the lock lever andprovided with a head adapted for engagement with the operating lever,and a link connection between the head and operating lever, theoperating lever serving through the medium of the links to actuate theconnecting rod in one direction, and by engagement with the head of theconnecting rod to actuate said rod in an opposite direction, as and forthe purpose specified.

2. In a window sash fastener, the combination, with a window frame, asash having central pivots in' said frame, and a rack horizontallylocated above the window sash adjacent to one of its pivots, said rackbeing secured to the window frame and provided with a series ofapertures in one of its members, and a stop adapted to limit themovement of the window sash when opened, of a lock lover, a pivotedblock in which the said lever is adjustably secured, the pivot blockhaving pivotal connection with the window sash, a looking pin adjustablysecured upon the lock lever and adapted to enter the apertures in therack, an operating lever of angular construction fulcrumed upon thewindow sash, a connecting bar having an opening extending through it,the end portions whereof are made flaring, one end of the locking leverbeing adjustably passed through the said opening, a head adjustablylocated at the lower extremity of the connecting rod, adapted to beengaged by the operating lever, and a link connection between the headof the connecting rod and the operating lever, said connection beingmade near the junction of the members of the operating lever,substantially as and for the purpose set forth.
